摘要：

The Lambda(0) polarization is analyzed with the experimental data in S + Pb collisions at energy 200 GeV per nucleon, which were produced at SPS of CERN. The small polarization value and the correlation between the transverse polarization and transverse momentum were obtained in Feynman parameterx(F) > 0, x(F) < 0 and all x(F). The results show that the non-polarization of lambda appears in the region of larger transverse momenta, say, at 1 - 2 GeV/c in P-tau. The origin of Polarization reduction are discussed.
